- The input message must have a termination character. Max 128 char.
- Parsing the content is done in the action string in the Event Handler
  • Context parameters
- %edi is the input text where termination character is excluded
- %sev is the EDI port (sub-event)
  • Useful macros and statements
  • %scutc - Extract substring by byte (character) position
  • %scutf - Extract field, fields defined by delimiter character
  • %sscan - Scan for string, extract rest of string after first match
  • %scmp - Compare strings
  • TMP - Set temporary variable

Example

EDI - External Data Input (3).jpg

The rule below will allow you to issue commands to EDI port like this:

  • Input command on EDI serial port: connect,101,103
- Generates internal command $CALL L101 L103
  • Input command on EDI serial port: disconnect,101,103
- Generates internal commands $C L101
tmp 0 "%scutf(%edi,\,,0)"
tmp 1 "%scutf(%edi,\,,1)"
tmp 2 "%scutf(%edi,\,,2)"
if %scmp(%tmp(0),connect)
 $CALL L%tmp(1) L%tmp(2)
 stop
endif
if %scmp(%tmp(0),disconnect)
 $C L%tmp(1)
endif
